### Definition structure
The following is a list of accepted members within an AutoRespond definition:
* regex (*string* or *string array*) - **Required.** Regular expression pattern(s) that will invoke the response.
* reply *(string)* - The message to send out to the channel in which the response was invoked.<sup>1</sup>
* exec *(string)* - Command line path and optional parameters to an external program. The program's output will be sent to the channel in which the response was invoked.<sup>1</sup>
* ratelimit *(integer)* - The amount of time in seconds in which the response may not be triggered again within the same channel. Defaults to 20.
* reply (*string*) - The message to send out to the channel in which the response was invoked.<sup>1</sup>
* exec (*string*) - Command line path and optional parameters to an external program. The program's output will be sent to the channel in which the response was invoked.<sup>1</sup>
* ratelimit (*integer*) - The amount of time in seconds in which the response may not be triggered again within the same channel. Defaults to 20.
* RandomChance (*number*) - A value between 0 and 1 representing the percent chance for the bot to respond to the corresponding trigger. Defaults to 1.0 (100%).
<sup>1</sup> It is **required** to have either *reply* or *exec* specified in a definition.
